Peabody Resources Ltd 2000 Public Statement
Company Progress
The results of Peabody Resources Limited’s (PRL) participation in the Greenhouse Challenge Programme have been reviewed and revised as necessary.
In the year ending June 1990, the greenhouse gas emissions from PRL’s Australian coal mining operations were approximately 150,150 tonnes of carbon dioxide equivalent global warming potential (CO2 GWP). PRL noted that emissions per unit of production (Bank Cubic Metre Total Movement) and per tonne Run of Mine (ROM) coal had declined between 1990 and 1995 primarily due to continuous improvement programmes.
PRL has had in place a substantial expansion programme between 1990 and 2000 which has brought about the start up of the new Bengalla Mine and an increase in coal production from the Warkworth mine. Total material movement by PRL’s operations has increased by 96% from 47.1 million BCM to 92.35 million BCM and ROM coal production has more than doubled from 7.2 million tonnes to 18.9 million tonnes.
In its original Cooperative Agreement covering Ravensworth, Warkworth and Bengalla mines, PRL committed to:
 an 8% reduction in CO2 emissions per BCM TM 1 from Energy Use between the years 1990 and 2000, and
 a 15 % reduction in CO2 emissions per tonne ROM from Energy Use between the years 1990 and 2000.
Total emissions for the group were projected to be 292,936 tonnes CO2 GWP in the year ending June 2000. For Ravensworth and Warkworth mines, productivity improvements and individual projects have achieved a further 10 % average reduction in the kg CO2 per BCM from Energy Use by June 2000. The Bengalla mine has been designed and built to be energy efficient to enable a 20 % reduction in the kg CO2 per BCM from Energy Use by June 2003 based on typical mining industry benchmarks.

Emissions Update
Emissions for the original three mines for the current reporting year ending June 2000 were 307,491 tonnes CO2 GWP which include fugitive and non-fugitive emissions resulting from Peabody Resources Limited’s mining business operations. Whilst these emissions are greater than the predicted emissions for the Group, at an individual mine site level, Peabody Resources Limited has met its Greenhouse Challenge commitment.
On a per unit of production basis, Peabody Resources Limited continued to perform within the objective to decrease greenhouse gases per unit of production. In 2000, these emissions have been lowered to a yearly average of 2.65 kg CO2/BCM TM and 15.1 kg CO2/t ROM. These latest figures differ from the figures projected in 1999 as a result of revisions to the emissions inventory and changed production rates between the individual participating mines.
In August 1999, PRL took over the management and operation of Moura mine in Queensland which included the Seam Gas plant. Net emissions from Moura mine for the current reporting year ending June 2000 are 250,100 tonnes CO2 GWP which include fugitive and non-fugitive emissions. Emissions resulting from the operation of the Seam Gas plant for the current reporting year ending June 2000 are 8,400 tonnes CO2 GWP which include all methane that has been flared or vented.
Emissions Savings and Achievements
PRL revised the estimate for the year 2000 emissions to be 292,950 tonnes CO2 GWP. Without the actions taken under the Cooperative Agreement, annual emissions in the year ending June 2000 would be 363,378 tonnes CO2 GWP or higher by 70,442 tonnes CO2 per year (using 1990 as the base year).
Actual savings in the current year from projects and continuous improvement activities amount to 55,887 tonnes CO2 using 1990 as the base year.
The total cumulative savings in emissions between 1990 and 2000 are calculated at 258,039 tonnes CO2 GWP.
Emissions Abatement
PRL is pleased to announce the production of Emissions Abatement through the operation of the Moura Seam Gas plant. For the reporting year ending June 2000, methane captured and processed by the plant amounted to abatement of 435,270 tonnes CO2 GWP which otherwise would have been vented to the atmosphere.
PRL plans to significantly increase production of seam gas from approximately 3,000 GJ per day to 18,000 GJ per day.
Adjacent to Warkworth, construction works for the new Redbank Power Station have commenced. The power station will utilise coal tailings waste from existing tailings ponds and directly from Warkworth’s Coal Handling and Preparation Plant. Greenhouse gas emissions will be avoided that otherwise would be released through the need to mine and utilise an equivalent amount of coal for use in domestic power generation.
